概括
这项研究发现,黑人非洲人和白人护理学生之间的自然保湿因子 (NMF) 含量没有显著差异,除了白人学生的高histidine水平,这表明类似的皮肤状况易感性.
科学领域:
- 皮肤病学和皮肤生理学
- 皮肤屏障的生物化学
- 皮肤成分的种族差异
背景情况:
- 有限的研究存在于皮肤屏障功能和自然保湿因子 (NMF) 之间的黑暗和浅色素的皮肤之间的差异.
- 南非的医疗保健工作者主要是黑人非洲人,强调需要了解他们的皮肤生理学.
- 在护理学生中评估NMF可以揭示对皮肤疾病的潜在敏感性.
研究的目的:
- 量化和比较黑人非洲,混合种族和白人护理学生的NMF含量.
- 调查与色素相关的皮肤屏障成分的潜在差异.
主要方法:
- 带剥离被用来从49名白人,32名黑人非洲人和5名混合种族的护理学生的主导背部手上收集样本.
- 测量了包括histidine (HIS),pyrrolidone carboxylic acid (PCA) 和urocanic acid异构体 (t-UCA,c-UCA) 在内的NMF成分.
- 细胞因子IL-1α和IL-1RA也被量化以评估炎症标志物.
主要成果:
- 在黑人非洲和白人护理学生之间没有观察到PCA,t-UCA,c-UCA,IL-1α或IL-1RA的统计学上显著差异.
- 与黑人非洲学生相比,白人护理学生的histidine (HIS) 水平显著更高 (p=0.001).
- 黑人非洲学生 (p=0.0002) 的总尿酸与希斯提丁的比率 (总UCA/HIS) 显著更高.
结论:
- 白人和黑人非洲护理学生之间的NMF含量在很大程度上是可比的,除了胺水平.
- 歇斯蒂丁水平的变化可能表明歇斯蒂达酶活性的差异,可能与皮肤pH值和色素有关.
- 进入职业生涯的护理学生可能会表现出与NMF相关的皮肤疾病的类似易感性,而不论种族.

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
